I have decided to sell my BBK ceramic longtubes and offroad X-pipe and go with a set of Cook's. I never installed them but have had a set of these on my car before and everything fit fine. The headers are in very good shape with no dents or dings. The X-pipe has a few scrapes but also no dents or dings. Its a nice looking set. I'm asking $400 plus shipping. I'll throw in a new set of O2 sensor extensions also. PM for more info. Thanks!
